The two most common categories of process responses in industrial manufacturing processes are self-regulating and integrating. A self-regulating process response to a step input change is ...

Proportional, integral, derivative (PID) position servo-loop tuning can be daunting. However, one simple technique works well for most systems. Chuck Lewin • Founder and CEO | Performance Motion ...

The tuning of proportional-integral-derivative (PID) control loops was an important change at HollyFrontier’s Navajo Refinery in Artesia, N.M. Its hands-on, “mandraulic” culture was no longer cutting ...

Suppose you're called into the control room to correct an alleged loop tuning problem. Probably the worst thing you could do is to immediately begin changing a tuning parameter. There are several ...

Control loops incorporating proportional, integral, and differential (P, I, and D) factors have become standard functions of motion controllers. Many of the latest controllers also offer feed-forward ...

Plant engineers and technicians are frequently asked to tune the controller when a control loop’s process value has prolonged or significant excursions from the set point. But in many instances, no ...

Except, that is, “when you consider the aging workforce and the institutional knowledge of processes and instrumentation that has been slipping away.” Thus, advances in ...

Let's presume that we have selected the valves and the transducers and even installed a controller. We now need to determine the controller settings - a practice that ...

Optimizing power plant control systems can be challenging, but new tools are available to simplify and improve the process. On this episode of The POWER Podcast, Executive Editor Aaron Larson spoke ...
